The characteristics of Glass :
• Scratch-resistance: Glass is not easily scratched
due to its high density.
• High-transmission: It comes with smooth surface
providing high transmission for clear view, anti-dust.
• Low-glare: Glass lenses feature low glare to reduce
eye fatigue when used for long times.
The characteristics of Acrylic :
• Light-weight: The weight of Acrylic is only half of glass.
• Anti-impact: The impact strength of Acrylic is 7-18 times
higher than that of glass.
• High-transmission: It has excellent transparency
characteristics and transmission is better than glass.
